I had a fairly major spinal op this year, and certainly for quite a while I couldn't really manage anything much at all, and in the early days I kept nodding off throughout the day. It wipes you out to the extent you can't even think about things, and even conversation can be an effort. I would send a card, and send texts offering to help etc but don't overdo it. I would doubt your friend is offended, just exhausted by the surgery.
Why do people lie online are they living a fantasy or winding us up?
